The invention discloses a fine grit authority management method in an
information system. The method includes the following steps of (1) establishing an authority type
list, wherein the authority type
list comprises authority type IDs, authority types and other fields, and authority is divided into the different types of menus, interfaces, operations, flow processes and data; (2) establishing an authority
list; (3) establishing a role list, wherein the role list comprises role IDs, role names and other fields; (4) establishing a role authority list, assigning the authority to roles, recording the authority assignment into the role authority list, establishing users and assigning the users to the roles; (5) establishing a user list; (6) establishing a
user role list and assigning the users to the roles, wherein the users can correspond to a plurality of roles; (7) achieving authority management of fine grit by inquiring the authority the users have in real time in the process that users log on and operate a
system. The fine grit authority management method can achieve complex authority management of menus, operation buttons, flow processes, data and the like with low
system overheads by applying the
database technology through user and
role management.
